I started hearing a ticking noise in my engine a short time ago. It got worse as the car warmed up. I took it to the shop thinking that the valves needed to be adjusted. They told me that my valves cant be adjusted(why not?). They put the stethescope(spelling?)all over the engine and found that the sound was much louder on the fuel pump. Its a napa fuel pump with about 2,500 miles on it, so I dont know if it could be bad already. Anyway, what do you suggest? Also, I do plan on changing the oil(maybe even to royal purple) to see if that solves the problem. The motor (289) was just rebuilt and has around 2500 miles on it.

Is it a hydraulic or solid cam? Why can't the rocker arms be adjusted? We need moe info as it is doubtful that your fuel pump is making that much noise. Maybe the cam eccentric is coming loose and making the noise. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00, '01, & '02 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

All I really know about the cam is that it is stock to a C-code 2bbl 289. My engine is a c-code 289 internally, but I've added an aluminum intake with a 4bbl and headers. The noise isn't that loud right when the car is warming up: At the initial cold crank, it ticks loud and real fast about 5 times, then is hardly noticeable, after driving the car for about 15-20 minutes, the sound gets much louder, it isn't extremely loud, but its enough that I can hear it inside the car. It speeds up and slows down with the rpms.

make sure that you dont have an exhaust leak between the headers and the head. header bolts are notorious for backing out. sometimes a leak will sound exactly like valvetrain noise. just a thought.------------------ mike r racing is real everything else is just a game. 81 capri-7.51 @89mph 1/8 1.54 60 ft. http://prestage.com/site/site_display.asp?SiteID=141

dont most stock small-blocks with hydralic cams use the "positive stop" rockers(the ones that you just tighten down)if thats what you have, thats probably what they meant by not being able to adjust them.could be a partially collapsed lifter or capri man may be right.a loose header or a slightly burned gasket can make a funny sounding tick.good luck64 fairlane lots of fiberglass even more bondo

If it's at engine speed then it's not in the valve train. It's probably a wrist pin or a piston slap. Maybe even a rod knock.

What does the oil pressure look like cold vs when it has warmed up? At idle...Rick

Had the exact same problem with my 65 fastback 289 just after I bought it. Turned out to be a cracked piston , but , I knew I was going to rebuild the motor when I got the car so no big deal , just did it sooner then I was expecting to do it.Sorry for the bad news if this is what is wrong with your car.

oil pressure tends to be a little high. Could it be the fuel pump? The motor was just rebuilt 2500 miles ago. What is a wrist pin, a piston slap, and a rod knock? The headers are hooker competition.

Don't totally rule out the fuel pump. I had a new Holley mechanical pump that knocked. The lever developed slack and every stroke it sounded like a lifter loose. Holley quickly replaced it. Its nice to live in the same town. Also the fuel pump eccentric could be loose also. Both can be checked by removing the fuel pump.Mike
